Open Grounds

Open Grounds is building a transparent investment infrastructure for income-generating sports venues such as futsal, padel, badminton, and tennis courts.

Venue owners can raise capital by offering a portion of their distributable net profit rights to investors rather than selling the entire business or relying solely on traditional loans. Investors receive digital tokens representing those economic rights and can participate in the venue's verified operating cash flow.

What makes Open Grounds different is the connection between the physical business and the digital investment layer. Court bookings, walk-ins, and other venue transactions are captured through Open Grounds' Point-of-Sale and reservation infrastructure. Revenue data is then reconciled with digital payments and used to calculate the venue's monthly profit waterfall. Pasted markdown

Smart contracts act as an independent execution layer for the economics of each venue, including token supply, investor allocations, monthly distributions, lock periods, dispute states, and sell-back requests. Critical decisions use a 2-of-3 approval model between Open Grounds, the venue owner, and an independent verifier, reducing the ability of any single party to manipulate the outcome. Pasted markdown

The user experience is intentionally Web2-like. Investors sign in using email or social accounts, pay through fiat rails such as QRIS, and do not need to manage seed phrases, ETH, or gas fees. Blockchain operates in the background as the settlement and enforcement layer. Pasted markdown

The long-term goal is to make operating sports assets more transparent, investable, and accessible while giving venue operators a new financing channel backed by actual business performance.

During the ETHJKT 2026 hackathon, we built the core Open Grounds stack end-to-end.

We developed and deployed the smart contract architecture on Ethereum Sepolia, including AttestationRegistry, VenueSeries, and SeriesToken. The contracts manage multi-party attestations, venue-specific profit distribution logic, compliant token allocation, lock periods, and investor sell-back flows. Pasted markdown

We also built the investor and venue-owner web platform, integrated an Open Grounds cashier/PoS and court-reservation system, implemented AI-assisted KYB and risk analysis, connected Xendit Sandbox for fiat payments, and integrated Didit for investor KYC. Pasted markdown

The smart contract suite currently passes 65 automated Foundry tests, including attack tests, invariant tests, supply-preservation checks, pool-conservation checks, and security regression tests. Pasted markdown

The platform and PoS applications are already running as working demos, and the hackathon work covered the contracts, web application, verification pipelines, shared economic modules, and database schemas.

Open Grounds has not raised any external funding yet.

The project is currently bootstrapped and pre-funding, with no equity round, token sale, grant funding, or institutional investment completed to date.

Current focus is on validating the product, legal structure, venue onboarding model, and real-world pilot before pursuing external fundraising.
